Colours - Rendering

Hi all
We are looking to swap over to BSB very soon but one small (and probably simple thing) is how to do the rendered drawings in BSB. In autocad we used the "mat" command and then applied the colours to certain parts as needed. Sometimes different directions of grain on certain parts or another colour
In BSB the command brings up a box where we can see the colours of materials we have added but I'm not sure on how to apply them to the 3d objects. Drag and drop doesn't work and i'm sure there is an easy way

thanks
